2012 IBC Door Assembly Rating Table
The door assembly rating table (currently 715.4) in 2012 IBC adds new columns that provide additional end-use information and limitations, and illuminate important differences in the permitted uses of fire protective and fire resistive glazing. One new column spells out size limits for vision panels which vary based on the application and whether or not the FRG is fire protective or fire resistive. A second new column outlines the required fire rating and where fire resistive rather than fire protective glazing is required in sidelites and transoms. Click here to download the revised table. Here are highlights:
2012 IBC Fire Window Rating Table
In the 2012 IBC, the fire window assembly rating table (currently 715.5) is revised to clearly identify where fire resistive glazing (tested to ASTM E-119 or UL 263) must be used to block the transmission of radiant heat. Click here to download the revised table. Here are highlights:
Other Code Changes in 2012 IBC
There are two other significant changes in the 2012 IBC related to FRG applications, marking and labeling.
Revised Label Marking Table
The 2012 IBC revises the label marking table (currently 715.3) to require letter designations corresponding to test standard(s) to which the product was tested. Click here to download the revised labeling table.
Fire Protective Door Vision Panels Limited in Size
The 2012 IBC removes an exception for fire protective door vision panels larger than 100 square inches in fully sprinklered buildings. Why? Because sprinklers do not always work, and because it is important that building occupants be protected from the dangers of radiant heat when exiting a building in a fire. The new IBC emphasizes that large vision panels in exit enclosures and passageways must be fire resistive tested to the ASTM E-119 or UL 263.
